I am amazed that both of you (who posted above)find it easy to use monofiliment thread! I just did a tiny sample since I'd like to use it for FMQ, especially if the bottom thread pops up to look like tiny hand stitches. However, I couldn't get it to stitch smoothly (with no puckers).
So what is your secret? What type of thread do you use on the bottom? Do you adjust your tension up? or down?
